I have an unanswered question about BPL. Where I live has a very old
power
line system, full of splices and corrosion. How will splices affect the
1) the
internet signal and 2) RFI?

The internet signal will be crappy and subject to interruption by static
from all kinds of sources. RFI generation will be severe. I do not know
whether the splices and corrosion will make it worse but it certainly won't
help matters.

A lousy splice could well act as a completely non-linear diode
detector and spew even more garbage everywhere up and down the whole
RF spectrum. It just keeps getting worse.

As to power line physical specifics kindly consider: To to a large
extent the radiated interference the BPL ISP's might bless us with, if
it ever gets off the ground, is dependent on the physical realities of
the line configurations they use.

Roll back decades ago and the phone companies rather easily beat their
interference problems (crosstalk for one) eons ago by using twisted
pairs of conductors to move comms along their wires. Twisted pairs of
conductors are generally inclined to reject incoming interference and
equally are not particulary inclined to radiate whatever signals they
might be transmitting from here to there analog or digital yes? Of
course. Goes back to some guy named Maxwell, has something to do with
the 3D electromagnetics right-hand and left-hand drive ya batty
"rules" he "discovered".

So it's become quite obvious to me that BPL and HF ham radio could
co-exist quite peacefully on the bands after they install their 3Ø
13Kv twisted pairs.
